. livery Mechanism for Printing-Machines,

fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present improvements relate in a general sense to that class of stapling mechanisms especially adapted for attachment to a web-printing machine to form a part of the delivery mechanism thereof, whereby the plicated material in the form of webs or sheets may be bound together in packs on the line of ultimate folding thereof by means of staples made and set therein during the onward progress of the said plicated packs for final delivery, and thus form a completed product, such as a pamphlet or newspaper,whose leaves are bound together in the form of a book-like product. In a general sense the type of such machines is comprehended in Patent No. 510,528, and more specifically the improved machine is of the class in which the staple forming, presenting, and inserting mechanisms are contained within the confines of a rotary carrier supporting them, which carrier also supports the wire length supplying means delivering material to form the staple,

which class has its type disclosed in Patent- A practical embodiment illustrative of this invention is shown in the accompanying drawings, as follows: i

Figure 1 illustrates by an end elevation and Fig. 2 by a side elevation so much ofa delivery apparatus of a printing-machine as is necessary for an understanding of the relation of the stapling mechanism thereto. The remaining figures, except '11, are enlarged views. Fig. 3 is a sectional end elevation of a portion of the carrier supporting the stapling mechanisms, in elevation, sufficient being shown to include one of the two sets of stapling mechanisms supported by said carrier. Fig. 4 is a transverse sectional plan view on a part of said stapling mechanism. Fig. 5 is a plan view of one set of said stapling mechanisms. Fig. 6 is a side elevation 'of the same attached to the carrier-shell, shown in section, as seen looking in the direction of the arrow 6 in Fig. 5. Fig. 7 is a plan view of a detached detail thereof. Fig. 8 is an elevation, and Fig. 9 a sectional plan view, of parts of the stapling mechanism rendered perspicuous by the omission of others. Fig. 10 is a plan view of the wire-feeding mechanism, and Fig. 11, an end elevation of the carrier, showing the relation of the wirereels thereto.

While the means for supplying the plicated material to the stapling mechanism may be any of those set forth in the above-named patent, illustratively that means is here shown as a longitudinal folder F, having guiding-rollers or external turners and nipping or fold-layin g rollers 7 O 80, over which many webs, as'W E BjS, are shown as traveling, said longitudinal folder being. of that construction described in Patent No. 331,280. These nipping-rollers are geared together to run in unison, one of their pinions 79 being shown in Fig. 2.

The plicated material P is so delivered to the stapling mechanism as to pass between the rotating carriers AC, which support the stapling mechanisms, the carrier C being sup plied with duplicate sets of stapling mechanisms for feeding wire thereto, cutting the same into staple lengths, forming the said legs into staples, presenting them in setting position, and inserting them through the running material, while the carrier A supports alike number of staple-leg-clenching devices, whereby said staple-legs protruded through the material are bent or clenched down there on. These carriers might be sufficient only to act as carriers for these stapling mechanisms, but as it is preferable for compactness of machinery, the room for which is often limited, said, carriers are also made to support cutting mechanisms for severing the webs into sheet lengths and with folding devices for folding the same, and as these carriers are made double, also, so as to operate upon two sets of sheets in one revolution, these carriers are supplied with double sets of stapling mechanisms andwith double sets of cutting and folding mechanisms, circumferentially considered, and for the reason that the stapling mechanisms are so arranged to form a binding-seam transversely to the run of the material the stapling mechanisms are also multiplied in the carriers in a lougitudinal directipn, two sets being so arranged as the selected number sullicient for the width of the material shown as operated upon.

As the stapling mechanisms are all constructed alike, a description of one set will now be given in detail, it being understood that the description thereof and the letters and figures of reference applied thereto may be read upon any of the other duplicate sets for an understanding thereof.

The stapling mechanism consists in a broad sense, first, of a forming-die, as 40, stationairy with respect to the rotating carrier C; sec- 0nd, of a reciprocating former, as 41, whereby a wire length is formed into a staple; third, a rotating staple-transferrer that is provided with a multiplicity of staple-receiving pockets, into which the formed staples are successively delivered, which transferrer transports said staples from the forming-point to the delivery-point, and, fourthly, of a reciprocating setter or driver 43, whereby said formed staples are inserted or driven through the running material when the carrier C has moved the stapling mechanism to the setting point for the staples. (See Figs. 8 and 9.) This forming-die consists of a block pierced longitudinally with a wire-guide slot for the introduction of the wire and transversely with a recess for the passage of the former 41,said slot being enlarged rearwardly at each end of the die 40 to permit the (ranting of the ends of the wire length during their formation into staple-legs and said recess being made sufficient to provide at the side of the former spaces for accommodating the staplelegs in their formation. (See Fig. 0.)

The stapling mechanism and supports for its moving parts are held stationary with respect to the carrier 0 by means of brackets 101 102, secured to the inner face of the shell of the carrier. (See Fig. 3.) The former 41 and setter or driver 43 are connected together, so as to move in unison, by means of a slide 45, from which they project laterally, which slide moves in a way 46, supported by the bracket 102, being driven by an arm 51, connected with it, having a bifurcated end by which it is guided by the shaft 5, and be ing provided with a friction-bowl laterally extending into a groove of a cam 103.

The wire from which the staples are to be made is carried by a reel 47, (see Fig. 11,) from which reel the wire is led between feeding-rolls 30 31, passes through a guide, and thence to the die 40. The wire is intermittently fed forward a staples length until its end is arrested by a stop-plate 44 by the retative movement of the rollers 30 31, accomplished by means of a segment 32, vibrated by a cam 33 on shaft 5, which is rotated by means of a wheel 34, which is driven by meshing with the toothed wheel 35, encircling the main shaft, fast 011 a sleeve secured to the side frame, said segment 32 engaging with a pinion U, which carries a ratchet-wheel 36, with which cooperates a spring-seated pawl 37, that is fast to the feeding-rollers 30, said feedingrollers operating by frictional contact when driven by the ratchet to properly advance the wire.

The slide 45 also carries a cutter 9, which in cooperation with the receiving end of the die 40 operates by a shearing action to sever the wire and detach a staple length thereof just as or immediately before the former 41 contacts with said wire length in the operation of forming it into a staple. Each staple as formed is by the continued forward movement of the former 41 thrust into and delivered in one of the pockets 10 of the transferrer 42, the transferrer standing still during this operation.

The transferrer 42 turns 011 an axis supported by the bracket 101, which is in such a position that a portion of its periphery protrudes through the shell of the carrier 0 and is intermittently rotated through a step-bystep movement accomplished by means of a ratchet-wheel 38 it carries, through which it is driven by a pawl 48, hung to a vibrating arm 49, which arm, journaled on the shaft of the transferrer, is vibrated by an arm 3!), that is bifurcated to embrace a shaft and provided laterally with a friction-bowl that runs in the groove of a cam 104. As each step movement is finished its position is maintained by a spring-pawl 52, whose rounded end presses into a suitably-formed recess near one edge of the periphery of the transferrer. At each step-like movement the pockets, one after another, are supplied with made staples, said staples as they are inserted in these pockets having their crowns pointed toward the place for setting the same. This inverted position of the staples is gradually reversed as the transferrer makes its rotation, so that when a pocket loaded with the staples is presented at the periphery of the carrier 0 it has its legs pointed outward. The rotative movement of this transferrer is so timed that when a loaded pocket is moved by the carrier 0 to the point for the insertion of said staple the said transferrer will have ceased to rotate and be stationary with respect to the carrier, with said poeketalined with the setter or driver 43, at which time a forward movement of the setter 43 and former 41 will simultaneously be made, the one to thrust a made staple outward through the material and aid in clenching the same and the latter to form a new staple and load a pocket therewith.

The carrier A is provided with an appropriate numberofsetting or clenching dies, and is geared to the carrier 0, so that the two carriers run in unison, one of their connectinggears 110 being shown in Fig. 2. Each clenching'die in this case is at the end of a bar 15, fastened to the shell of the carrier in the proper position.

From the foregoing it will be understood that these operations of feeding the wire forming the staple and transferring it to the setting position are constantly going on within the carrier 0 at an appropriate speed, while the carrier is constantly rotating at a higher speed, suited to that in which the material to be stapled is moving, and that when a suitable length of material-has passed between the carriers A 0 one or the other of the staple-transferrers will be presented at the setting point, or where the carriers A 0 run nearest in contact, the transferrer 42 then being stationary and one of these pockets presenting a made staple in position to be set, and

that at the appropriate moment to which the mechanisms are timed the settingtool or driver 43 will be quickly advanced to make contact with the said staple, drive the same outward, insert it through the passing material, and cause its legs to enter into the die 3 of the carrier A, and thus be clenched onto said material, which material thus stapled will pass onward for delivery.

Of course'the finished material might pass from the carriers A O to any delivery mechanism or first to a cutting and then to a folding mechanism of any suitable construction; but as it is convenient, as before stated, to combine cutting and fofdin g mechanisms with the carriers which support the stapling mechanisms it will be understood from the state of the art, as set forth in the first-named patent, that the material P will be temporarily held on the periphery of the carrier A and be made to overlap a folding-blade, as 75, and that when said folding-blades arrive over a pair of folding-rollers said foldingblade will be projected to double or fold said stapled product into the nip of said foldingrollers, which folding devices are illustrated in Patent No. 171,186, and which folding operation is fully described in the first beforementioned patent; also, that when the proper 2.
